Insects are among the greatest threats to agriculture. Tennessee farmers have seen some pests disappear, but in the process, new ones emerged, and they are attacking fields.

Gnats (Black Flies) 
In Tennessee’s warm months, gnats are a nuisance to people and animals. UT researchers are working to reduce the population by eliminating them before they’ve hatched from rivers and streams.
